1 Claim.

The invention relates to apparatus for supporting the supply conductorof a reciprocating electric motor.

The object of the invention is to provide a simple and effectivearrangement for carrying an extensible electric cord for-supplyingcurrent to a reciprocating electric motor. More particularly, thepresent invention provides a simple and effective arrangement forcarrying a cord in the form of a series of loops slidable along a xedsupport from a contracted to an extended position.

The invention further consists in the several features hereinafter setforth and more particularly dened by claim at the conclusion hereof.

In the drawings:

Fig. 1 is a plan view of the device embodying the invention, parts ofthe apparatus being broken away and the cord being shown in extendedposition;

Fig. 2 is a side elevation View of the device embodying the invention,the cord being shown in contracted position;

Fig. 3 is a detailed perspective View of a part of the cord support.

In the drawings, the numeral 5 designates an electric motor Which ismounted on a carriage 6 v provided with wheels 'l running in channelguides or rails 8. The carriage 6 may be reciprocated or moved back andforth along the rails 8 by means driven from the motor 5, and in thepresent instance I have used the drive mechanism more particularly shownin detail in the prior U. S. Patent No.` 2,111,247,` to Victor Malueg,dated March 15, 1938, wherein the motor 5 has its drive shaft connectedby a pulley 9 and belt I0 with a pulley II on a shaft I2 which isconnected through suitable mechanism (not shown), with a shaft having apair of drums |3`mounted thereon and adapted to be selectively clutchedthereto, each drum having a cord I4 secured thereto at one end andanchored at-its other end to one end of the track frame I5. Thus whenone of the drums is driven, one of the cords is wound up and thecarriage is pulled in one direction along the track, and then when theother drum is driven, the other cord is Wound upfand the carriage ispulled in the opposite direction along the track.

The motor 5 runs continuously, and the direction of travel of thecarriage is reversed throughl mechanism` controlling the reversal oflthe clutches as more particularly shown and described in said patent. Itis to be noted that in the present instance the shaft I6 for the drumsI3 has an agitator mounted thereon which is always rotated in the samedirection and is arranged to work in a tank I8. The motor is fedwithcurrent from a source of supply'through a flexible cord conductorI9, one kend of which is shown associated with a current control switchIl and the other with the terminals of the motor. This cord |9 is longenough so that in one position of the carriage, said cord maybe arrangedin several coils 2|. Each of the coils 2| l0 is supportedfrom a fixedvsupport or rod 22 by a bendable metal member 23' which is provided witha tubular portion 24 slidably mounted on the rod 22 and a split tubularportion 25 in which the conductor I9 is mounted.' The sidesof thelvtubular portion 25 may be spread or bent out to receive the conductor I9and then bent back to closed position. The portion 25 is disposed at aslight angle to the part 24 so as to start the coiling of the conductorin the proper direction. With the above arrangement when the carriage tis at one end ofthe frame |5,'the` members 23 are arranged in abuttingrelation.` and` theloops or coils 2| are in their full open position.Then as the motor 5 moves the carriage l `25 l I desire `it to beunderstood that. this inven- 35 tion is not y,to be limited to anyparticular form or arrangement of parts except in so far as suchlimitations are included in the claim.` f y What I claim as my inventionisf" In a device having a reciprocating carriage and 40 an electricmotor mounted on said carriage for moving` the same, means forfurnishing vcurrent to saidmotor comprising a-flexible cord conductorconnected at 'one end tosaid motor and hav-f ing its other end fixed,a-rod extending parallel to 45 the path of movement of said carriage, aplurality of carriers, each of said carriers having atubular portionslidably mounted on said rod and a tubular split portion disposed at anangle to said first named portion and receiving and clamping 50 aportion of said conductor to said carrier, said. conductor being loopedbetween adjoining carriers.
